Web23 de fev. de 2024 · DNA persistence and DNA transfer are important features in the assessment of a crime scene. The question how long DNA may persist at a certain location is similarly important as the one how the DNA has been transferred to this location.

Our analyses of UNG-treated sequences revealed varying levels of DNA damage. In the 5- to 30-Kyr age range, low-GC Gram-positive bacteria with the capacity to form dormant endospores accumulated hydrolytic damage at the 99% confidence level (Fisher exact test, n = 95; P = 0.00008).

WebHá 2 dias · Moreover, ampC and vanA were detected in cultured bacterial strains of biofilm samples collected with modified stainless-steel Robbins devices from the DWDS in Mainz, Germany (Schwartz et al., 2003). The mecA and vanB genes, on the other hand, were found in total DNA that was directly extracted from biofilm samples (Schwartz et al., 2003). WebThe DNA must be supercoiled in order to fit into the cell. The length of the single DNA molecule needed to carry the 4000 or so genes of a bacterial cell is about 1.5 mm, and this structure is compacted into 0.2 μm 3! Thus, a stretched out bacterial chromosome is a thousand times longer than a bacterial cell.
WebIn direct contrast to in vitro based predictions, bacterial DNA and even culturable cells have been reported from various ancient specimens many million years (Ma) old [1-8].
